Please do not put unavailable characters first in mission units

In TB when you look at a mission, the mission units display starts by showing the units which are not available because they have been assigned to another territory. It would be more useful if it showed the units which are available first, and then the ones which are not.

Currently it seems to list the required units, then the units which are unavailable because of other deployment, then the rest of the units which fit the criterion in order by power, but with any units which do not meet the star requirement or have been used in another battle grayed out. It is a very complicated arrangement.

Would be simpler to put the required units, then units by power, with those units which are unavailable for whatever reason grayed out either in power order, or at end.
